Acoustic pollution can cause damage and negative effects on people's health. The human being is the cause of the various activities he performs, stories such as commercial and industrial activities, transport, construction and public works, etc.
The objective of this research is the evaluation and monitoring of environmental noise in the "Ciudad de Otavalo" study area, which is the urban center with the highest noise pollution in the region. To start the investigation, the points with the highest sound pressure found in the city were defined, establishing a range of results that were cataloged in maximum and minimum levels, measured in the different schedules established throughout the day.
Acoustic prediction maps for the city were prepared, with the Arc Gis 10.3 software by means of the interpolation of the data obtained, it was verified that the main emitter of environmental noise is the traffic that the city has.
The analysis and the respective recommendations were carried out through the design of the mitigation plan of the study area established in the different times of morning, afternoon and evening finding in its totality the data obtained exceeded the limits allowed by law. The main causes that influence the dispersion and increase of sound can be wind, temperature, and orography. People who are in these points can be exposed to the harmful effects on their health; it can be short, medium or long term.
